반응성 염료의 건열 고착 적정 시간에 관한 연구

Abstract

As the reactive dye is the one that is good in fastness, can obtain clear color, and is available for applying diverse dyeing methods compared to other cellulose dyes, it is being widely used in direct printing of cellulose textile such as directly textile printing, discharge printing, and resit printing. As the reactive dye, which possesses the big weight in the domestically dye production and export market, is the one that is locked in by causing chemical reaction with fiber, it forms a covalent bond between dye and fiber by responding with fiber in the dyeing process. This study aimed to experimentally research into a method available for applying to directly handicraft textile printing, and to examine the dry-heat lock-in time proper for the selected reactive dye, through theoretical consideration on characteristics and textile-printing principle in the reactive dye. After measuring fastness according to difference in dry-heat lock-in time, it suggested the proper dry-heat lock-in time through the results. To manufacture the hand-screen printing work that is clear in the printing of cotton textile and is available for long-term preservation by the reactive dye, it tried to offer the research materials on the process of developing and manufacturing textile design of using a dry-heat lock-in method. As for this study, given synthesizing the findings that were measured fastness according to a change of dry-heat lock-in time in the theoretical consideration on the reactive dye and in the cotton-textile printing process of the reactive dye, they are as follows. The appropriate lock-in time of the dry-heat lock-in method in the textile-printing process of the reactive dye showed the relatively excellent washing fastness and sunlight fastness given 1-minute processing of heat press at 150℃. The reactive dye is the one that is clear in color and that is good and excellent in all the fastness except washing fastness. Thus, to increase practicality, there is necessity of increasing reactivity with fiber by expanding scope in stability on hydrolysis of dye. An in-depth research is needed on simplicity of post-treatment process after dyeing.
